Ley Initiate

You've studied the natural magic of the world and learnt of
ways to harness it, or you might have come into contact with
a ley line or nexus, an event that altered your very being.

Leylines. When you gain this feat, you become attuned to a Lesser
Mana Ley Line. This attunement does not count against the
number of items you can attune to at a time, and it doesn't
end by you being more than 100 feet away from the ley line,
or if another creature attunes to the same ley line. You can
only be attuned to one ley line at a time, and if you attune to a
new one, the attunement with the previous one ends.
While attuned to a ley line, you always know the closest
direction towards its location as long as you're on the same
plane of existence as it. Over a short rest, you can attune to
another ley line (Lesser or higher) while you are within the area
affected by it. You can tap a ley line a number of times per day equal to your proficiency bonus.

Tap DC. You must attune to a Ley Line before you can tap it, and each Ley Line has a tap DC depending on its tier.

Mana Points. You gain a number of mana points equal to your proficiency bonus, representing your prowess over ley magic and your innate connection with the land. You can never have more mana points than your proficiency bonus, unless you gain extra mana points from feats that have this feat as a prerequisite. When tapping a Ley Line or Ley Nexus, you can use one or more mana points to gain a flat bonus to your roll equal to the number of points spent. You may also gain the option to use these points for "ley powers" granted by subsequent feats that have this feat as a prerequisite. You regain all spent mana points when you finish a long rest. In addition, once per day when you finish a short rest within the area affected by a ley line you are attuned to, you can choose to regain spent mana points up to your proficiency bonus.
